The NiceHash service for leasing and renting crypto hashrate has announced the addition of a new crypto algorithm to their list of supported algos – the Zhash algorithm or Equihash with parameter set 144,5. This algorithm is currently used as a PoW algorithm with Bitcoin Gold (BTG), Anon (ANON) and BitcoinZ (BTCZ) and other projects. The Zhash algorithm works by increasing the hardware requirements of Equihash to make the development of an ASIC appliance less viable and to put back GPU mining in control for the projects using this algorithm. Aside from support for Zhash on the marketplace for hashrate, mining Zhash is also supported through the latest NiceHash Miner Legacy (18.104.22.168) as well as third party miners of course.
Another popular service for renting and leasing mining rigs Mining Rig Rentals has been offering Zhash (Equihash 144,5) for quite some time, though the market there is usually smaller compared to what NiceHash is capable of providing in terms of hashrate. Apart from Zhash this service also offers support for Equihash 96,5 as well as Equihash 192,7 and Equihash 210,9 so if you need any of these you can check the MRR service as well.
